Product description
3.4 UE410-GU main module
The UE410-GU is a main module that can be used as an alternative to the UE410-MU. The
system configuration is stored in the main module (for further information please refer to
section 9.1 “Accepting the system configuration” on page 92).
Only one UE410-GU can be used per Flexi Classic system.
In order to increase the number of inputs, one or more UE410-8DI extension modules can
be used additionally.
To increase the number of outputs, an additional UE410-XU can be used (see section 4.12
“Grouping of subsystems” on page 78). A total of up to 12 Flexi Classic modules and one
gateway can be connected to the UE410-GU.
The UE410-GU makes possible a global emergency stop function for several stations con-
nected together that must each be equipped with a UE410-GU. If the global emergency
stop on a module is operated, the safety outputs on all modules switch off. To reset a glo-
bal emergency stop, the reset button must be operated on the same module on which the
global emergency stop was triggered.
A global emergency stop must always be reset manually.
Along with the global emergency stop function, on each module it is also possible to select
a local emergency stop function with or without restart interlock. The local emergency stop
only acts on the safety output on the related module. A local emergency stop can be reset
either automatically or manually.
The safety output Q1 always switches within the response time. A switch off delay as on
the UE410-MU is not possible with the UE410-GU.
Different programs for the local inputs can be selected with the aid of a rotary switch.
9 programs are available using which the following functions can be set:
• type of the safety sensors to be connected
• global emergency stop or global and local emergency stop
• automatic or manual reset of a local emergency stop
For further information see section 3.7 “UE410-GU programs” on page 49.
Subsequent changes to the program will result in a safety-related shutdown without
saving.
